Why does my power bank provide less power than expected?

Due to voltage conversion and heat loss, usable capacity is typically reduced by 30 - 45%. For example, a 15,000 mAh pack delivers roughly 8,250 - 10,500 mAh (3.6 V). This is an industry-standard specification.

How can I estimate how many times my device can be charged?

To estimate the number of charges: (Power bank capacity × 0.59) ÷ Device battery capacity. For example, a 15,000 mAh pack charges a 1,800 mAh device about 4.9 times, and a 10,000 mAh pack charges a 3,561 mAh device about 2.4 times.

Can I take this power bank on a plane?

Yes. This power bank can be carried on board, as its capacity is below the airline limit of 160Wh (43,243mAh). Please note that some airlines may have their own specific regulations.
